[GWSG] Arctic warming; US warming; Trump denying; US emissions fall; 100% by 2032; S FL salination; WAIS dwindles; Arctic CH4

[Tilley, Al]

1.  The Arctic climate is becoming consistently warmer, melting sea ice, ice sheets, and permafrost.  The changes are not necessarily linear.  Columbia's Marco Tedesco, who studies Greenland:  "I see the situation as a train going downhill."  https://www.washingtonpost.com/news/energy-environment/wp/2016/07/13/the-extraordinary-years-have-become-the-normal-years-scientists-survey-radical-melt-in-the-arctic/



2.  It really is getting hotter and more humid in the US, and it's going to get worse.  Florida faces the greatest increases.  http://www.climatecentral.org/news/sizzling-summers-20515?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+climatecentral%2FdjOO+Climate+Central+-+Full+Feed



3.  President Trump would be the only national leader denying the findings of climate science, and might very well be the only one not calling for climate action.  https://www.sierraclub.org/sites/www.sierraclub.org/files/uploads-wysiwig/TrumpVsWorld.pdf



4.  US CO2 emissions have fallen 21% since 2005 and are now just above 1990 levels.  Better building efficiency, more renewable energy installations, and regulation have helped.  (In many other countries, including those of the EU, emissions targets are calculated on a 1990 base.  Now we can join them with less embarrassment.)  http://www.climatecentral.org/news/efficiency-clean-energy-dent-co2-emissions-20527



5.  Salt Lake City has adopted an ambitious package of climate action goals which include 100% renewable electricity production by 2032.  http://www.ecowatch.com/salt-lake-city-makes-historic-commitment-to-100-percent-renewables-by--1921872817.html



6.  As rising sea levels contaminate S Florida's Biscayne aquifer with salt water, the region's source of water disappears and the Everglades suffers an ecological change.  http://www.npr.org/2016/05/25/477014085/rising-seas-push-too-much-salt-into-the-florida-everglades?utm_medium=RSS&utm_campaign=environment



7.  The hundreds of small glaciers on the western shore of the West Antarctic Ice Sheet are being eaten away by warm ocean currents.  http://www.climatecentral.org/news/warm-oceans-eating-away-antarctic-ice-20529?utm_source=feedburner&utm_medium=feed&utm_campaign=Feed%3A+climatecentral%2FdjOO+Climate+Central+-+Full+Feed



8.  Jason Box observes that methane from Arctic clathrates is indeed a great risk, but that we do not yet know the likelihood that it will be released in significant amounts, though several nations are studying the situation.  His comments come about eight minutes into the interview, which mostly concerns the Dark Snow project.  https://climatecrocks.com/2016/07/14/jason-box-urges-care-caution-on-arctic-methane-risk/  ?
